Application filed August 16, 1920. Serial No. 403,882.

To all whom it may concern:

Be it known that I, RALPH M. JACKSON, a citizen of the United States, residing at La Habra, in the, county of Orange and State of California, have invented a new and useful Fumi-gating Applicator, of which the following is a specification.

My invention relates to measuring devices and gasifiers for applying liquid gases for fumigating purposes under covered trees.

As one familiar with the fumigation of citrus trees, I am not aware of a similar device having the measuring means under the tree and cover-when in operation, nor with the measuring means operating with a uniform stroke, as will be found the basic principles of this device.

As far asI know in devices of this character, prior to my invention the measurement of dosage was controlled by means of I a graduated gauge, graduated in single ounces or units and permitting the-stroke of the actuating member to vary with the number of units measured, instead of accomplishing the measurement with a uniform stroke and-a fixed plurality of ounces or units per stroke, the means employed in the old means, especially for night work.

Safety in operation, uniformity of dos.

age, simplicity of operation and construction and light weight construction are among the objects of this invention. Other objects. will appear fromthe following description and the claims. v

Referring to the drawings generally;

Fig. 1 is a perspective side elevation of the complete applicator.

Fig. 2 is an enlarged sectional detail of the measuring means and gasifier taken on the line 22 of Fig. 3.

Fig.3 is an enlarged top plan view of the measuring means and gasifier.

Fig. 4 is a fragmentary top plan view of the sup-ply tank and a detail of the measure control attached thereto.

Fig. 5 is a side elevation showing the applicator in. use in connection with a covered tree.

The device comprises a supply tank 1' ranged at anappreciable distance at onev side of tank '1, and extends but a slight distance upwardly from the base of the device. By this arrangement the auxiliary tank and the mechanism associated therewith including the vaporizing apparatus, may be inserted beneath the covering over the tree to be fumigated, while permitting the tank 1, and the operating and controlling mechanism associated therewith to be positioned outside of the tree cover where the operator -may readily reach the same. Leakage in a device of this character is most likely to occur at the stufling boxes and joints forming a part of the measuring and vaporizing mechanism, and by placing this mechanism beneath the tree cover, any poisonous fumes escaping from the mechanism when in operation and subjected to pressure, will be prevented from reaching the operator.

' The auxiliary tank at extends across .the measuring and vaporizing mechanism, and a pump cylinder 9 is arranged in the auxiliary tank' at one side of the upper portion thereof, so that the auxiliary tank may extend upwardly in horizontal alinement with the pump cylinder and beyond The pipe 5- communicates with the auxiliary tank in vertical alinement with the same.

the portion of the latter, which extends up wardly in back of cylinder 9. A valve mechanism 6 regulates the supply from pipe and 11, said valve being actuated by a float 7 positioned in the portion of the auxiliary tank beyond cylinder 9.

A pump plunger 8 is provided in cylinder 9, and the action of said pump plunger is adapted to draw -liquid from auxiliary tank 4 to vaporizing nozzleslO and 11 -arranged above the pump. i

The pump is so arranged that its plunger reciprocates horizontally, and aside from other obvious advantages, with this construction the distance to which the measuring and vaporizing mechanism fextends upwardly from the base of the device is materially lessened. I

An operatinglever 12 14 on the side of sup-ply tank 1, and the upper end of the lever is provided with a handle 14 A connecting rod 13 is provided between the opposite end of the operating lever and the pump. The lever 12 is adapted to be swung back and forth through a guide way 15, and adjusting screws 16 and 17 are provided at the respective ends of the guideway so as to limit the stroke of lever 12.

A suitable handle 18 may be provided for carrying the entire device.

The supply tank 1, is filled with. liqpid gas after removing the filler cap 2, t en the filler cap is replaced and the valve 3 is opened permitting the liquid gas to flow into the auxiliary tank and float chamber 4:, through the pipe 5 and float valve 6, the float 7 controlling the flow of liquid. The measuring means and gasifier is placed under the edge of and inside of the cover,

.tank'outside of the cover.

pumped and measured from the auxihary leaving the operating means and the sup-ply The liquid is tank by the stroke of the pump plunger 8, in the pump 0 linder 9,. to the vaporizing nozzles 10 an 11, and thence delivered under the tree and cover. The operating lever with its fulcrum at 1% is controlled by the measure controller 15, which gauges the stroke and dosage. The stroke and dosage In case of odd ounces the operating lever is sprung into and stopped 'bythe notch 19,

which is midway of the stroke, accomplishing the measurement of one ounce. For example, if the requirements call for seven ounces the operator would make three and one-half strokes of the operating lever, the operating lever would then start the next application in the center ofthe stroke and should the next application require nine ounces, the operator would make a half stroke backor forth followed by four full strokes. The operating lever would then be left to start again on a full stroke.

The pump cylinder is, preferably enclosed in the auxiliary tank and submerged in the liquid. This is for the purpose of keeping the pump cylinder an equal temperature with the sensitive liquid gas material employed, which is quickly affected by slight change of temperature.

The supply tank is vented through the tubing 20 and the auxiliary tank is vented through the perforation 21.

With the measuring means under the cover when in operation, danger to the operator of deadly fumes leaking from stuffing ing member functioning outside of said cover,

measuring mechanism and vaporizing means measuring means to the vaporizing nozzles.
